DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 258,357, dated May 23,1882.

Application filed January 12. 1 882. (No model.)

vented a new and useful Improved Dumping- Wagon, of which the followingis a full, clear, and exact description. I r

The object of our invention is to facilitafe dumping the contents of awagon or cart.

The invention consists in adumping-wagon constructed with two adjustablecircular racks at the rear end of the box-supporting frame and acircular rack with an extensible arm at the front of this frame, andwith suitable gear- :5 wheels, sprocket-wheels, and a driving-chain foroperating these racks, whereby the box may be raised and inclined by thefront and rear racks; or the rear racks may be disengaged, so that thefront end of the box will be raised only, as will be fully described andset forth hereinafter.

. Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal elevation of our improved dumping-wagon,parts being broken out. Fig. 2 is a plan view of the supportingframe,the wagon-box being removed.

The wagon-box A is constructed with a false bottom inclined from thefront toward the rear, and at its rear end the box is provided with anopening and a spout, B, the opening being provided with a suitable dooror gate 5 for closing it. The box A rests on a baseframe, 0, which issupported by the axles and wheels in the ordinary manner. In the rearend of the base-frame G a transverse shaft, D, is journaled, and eachend of this shaft,

0 projecting from the sides of the frame 0, is

provided with an eccentric bushing, E, on each of which a largequadrant-shaped or circular rack, F, is loosely mounted in such a mannerthat this rack extends toward the front of the The upper arm of eachrack-frameFis provided at the free end with a short longitudinal slot,at, through which a pintle or stud, 12, passes into the sideof the boxA, as shown in Fig. 1. The quadrant or circular racks F engage withpinions G, mounted on the projecting ends of a transverse shaft, H,journaled :the wagon-box A, as shown in Fig. 1.

in the frame 0. On this shaft a cog-wheel, I, is mounted, withintheframeO,and engageswith a pinion, l, on ajournaled shaft, J, on whichis mounted a cog-wheel, J, engaging with a pinion, K, on a journaledshaft, L, provided atits end projecting from the side of the frame (3with a ratchet-wheel, L, and a crank, M, on which ratchetwheel L a pawl,M, rests. The shafts J and L arejournaled in one of the outerlongitudinal bars, 0, and in one of two longitudinal intermediate bars,0 of the frame G, .as shown in Fig. 2. A quadrant rack, N,

is loosely mounted between the middle bars,

0 on a transverse shaft, 0, of the frame 0. The upperarm of the quadrantor circular rack N is provided with sliding arms P, which can beadjusted and locked to project a greater or less distance from the outerend of the upper arm of the'quadrant or circular rackNbymeans of pintlesor bolts (1, or any other suitable or equivalent device. In the outerends of these arms P a wheel or pulley, Q, is journaled, which isadapted to slide in a longitudinal groove, R, in the front part of thebottoni of he quadrant-rack N engages with a pinion, S, on ajournaledshaft, T, near the front end of the frame O. Sprocket-wheelsUandVaremounted on the shafts H and T, respectively, and a driving-chain, W, ofany suitable construction, passes over these wheels U and V, as shown.

The operation is as follows: If the contents of the wagon-for instance,coals- 4s to pass from the wagon through a cellar -window or otheropening into the cellar, a chute must be used, down which the coals canslide from the wagon to this opening or cellar-window. The crank M isturned as indicated bythe arrow a,cai1sing the quadrant or circularracks F and N to swing as indicated by their arrows, as the two shafts Hand T, carrying the pinions G and S, are connected by the chain W. Theupper arm of the front quadrant or circular rack, N, is'lengthened moreor less by means of the adjustable arms I, and the front end of the boxA will be raised accordingly higher than the rear end. The entire box isalso moved to project from the rear end of the frame 0 a distance equalto the radius of the quadrants or circular racks F. It is not necessarythat the upper arm of the front quadrant or circular rack, N, belengthened; but we prefer to do so, as the front end of thebox A will beraised so much higher; but in place of providing the rack N with theadjustable sliding arms Pthe rack can be made larger than the rearracks, F, and a correspondingly larger pinion, S, must be provided. Whenthe box is thus raised, as shown in dotted lines in Fig. 1, the chute isplaced under the spout B and the gate or door in the rear end of the boxA is opened. The coals or other materials will slide down this chuteinto the cellar. If the coals are to be dumped upon the sidewalk or uponthe ground, the shaft D is turned about a halfrevolution by means of awrench or anysuitable key. The eccentric bushings E will move the racksF slightly toward the rear end ofthe frame 0, (the slots at permittingof thi's 'movementfl and these racks F will thus be disengaged from thepinionsG. If the crank Mism-owturned, the'front rack, N, only will beraised, as the racks F are not-engaged with thepinion's G, and the frontend of the box only will be raised, and will only draw the racks Fupward slightly.

lf the racks F and N are used to dump the box A, the rear end of thesame can be projected some distance beyond the curb-stone, so that noneof the contents of the Wagon will fall into the gutter in case the chuteis not used- Having thus described our invention, we claim as new anddesire to secure by Letters Pate'nt- 1 In a dumping-wagon, thecombination, with the supporting-i'rame C and the box A, of thequadrantsor circular racks F at the rear end-of the wagon and the quadrant orcircular rack N at'the front end of the wagon, and of gear-wheels foroperating these racks, substantially as herein shown and described, andfor the purpose set forth.

2. In a dumping-wagon, the combination,

,with thesupporting-frame G and the box A,

of, the rearquadrants or circular racks, F, the

, front quadrant or circular rack, N, gear-wheels,

sprocket-wheels U V, and the chain W, for operating the frontand rearracks simultaneous- 1y, substantiallyas herein shown and described, andfor-the purpose set forth.

3. In a dumping-wagon, the combination, with thesupporting-frame U andthe box A,

of the shaft D, the rear quadrants or circular racks, F, the shaft H,the pinions G, the front quadrant or circular rack, N, the shaft T, thepinion S, the sprocket-wheels U and V, the chain W, and of gear-wheelsfor operating the racks, substantially as herein shown and described,and for the purpose set forth.

4. In a dumping-wagon, the combination, with the supporting-frame andthe box, of circular or quadrant racks at the rear end of the wagon, acircular or. quadrant rack at the front end of the wagon, the front rackbeing provided with an arm adj ustably secured thereto, and ofgear-wheels for operating the racks, substantially as herein shown anddescribed, and for the purpose set forth.

5. In a dumping-wagon, the combination, with the supporting-frame O andthe box A, of the rear circular or'quadrant racks, F, the front rack, N,provided with sliding arms I, having a pulley, Q, at the outer ends, the

groove R in the bottom of the'box, at the front end of the same, and ofgear-wheels for operatingthe racks, substantially as herein shown anddescribed, and for the purpose set forth.

6. In a dumping-wagon, the shaft D, provided with the eccentric bushingsE, in combination with the body A, the frame 0, the quadrant-rack F, andmechanism for operating thesame, substantially as shown and described,whereby the said rack is adapted to be disengaged from the operating.mechanism, as and for the purpose set forth.

7. In a dumping-wagon, the combination, with the supp/orting-frame G andthe box A, of the front circular or quadrant rack, N, the shaft D,provided with eccentric bushings E, the circularor quadrant racks F,loosely mounted on these eccentric bushings E, which racks are providedat the upper ends with slots at, the pintles b, passing through theslots ainto the box A, and of gear-wheels foroperating these racks,substantially as herein shown and described, and for the purpose ofdisengaging the rear racks, F, from their pinions, so that the box willbe raised by the front rack only,

as set forth.
